Moonbeam compatibility with Ethereum is what makes it really useful, and is possible due to:
- Minimal Changes: developers can use existing Solidity smart contracts with no need to rewrite or reconfigure them.
- Unified Accounts, Addresses, and Signatures: use your existing Ethereum H160 accounts & ECDSA signatures to interact with Moonbeam
- Tap into the Most Integrations on Polkadot: use existing oracles, bridges, wallets, and other tools that are already building on Moonbeam
Moonbeam provides its connectivity between Polkadot Parachains
and other chains, via bridges. However, what makes Moonbeam Unique is that it allows developers to redeploy their existing smart contracts easily, using the same tools and integrations that they already use.
What Moonbeam essentially does is to allow developers with Solidity or Vyper-based smart contracts to "go multi-chain" and deploy their contracts also in the Polkadot ecosystem and many others. With the use of the platform permissionless decentralized applications (dApps) using familiar Ethereum development tools can be easily created, by ensuring that there is minimal change when front-end dApps are moved between chains. This can allow developers to bypass the scalability challenges due to the expense and constraints of congested networks like Ethereum's.
